Description

DETAILED DESCRIPTION OF THE INVENTION This invention relates to a steering device for a children's automobile, and particularly to a steering angle limiting device thereof.

In the case of conventional children's cars, the steering angle of the tie rods that steer the left and right front wheels is determined by installing a frame-shaped or pair of left and right stoppers near the center of the lower surface of the front wheel mounting frame at the bottom of the car body near the front. The vicinity of the connecting portion of the steering handle shaft is restricted by hitting this stopper.

However, in the case of such a structure, a separate stopper must be attached to the lower part of the front wheel mounting frame, so there is a problem in that manufacturing and assembly are time-consuming.

This invention solves the problems of conventional children's cars as described above by providing a restriction piece on the front end of the knuckle arm and bringing this restriction piece into contact with the contact surfaces on both sides of the vehicle body, thereby making it possible to control the front wheels with an extremely simple structure. To provide a steering restriction device for a children's automobile, which is capable of restricting the steering angle of a child's automobile.

The details of this invention will be explained below based on an embodiment shown in the accompanying drawings.

In the figure, A is a children's car, which consists of an upper body 1 and a lower body 2 made of plastic or the like, and has a pair of left and right rear wheels 3 and a pair of left and right front wheels 4, and the rear wheels 3 are driven by pedals 5. .

Reference numeral 6 denotes a metal front wheel mounting frame fixed to the front of the bottom of the lower vehicle body 2, and a circular annular bearing 7 is fixed to the center rear part of the frame by means such as welding. A shaft 8 is rotatably mounted, and a steering handle 9 is fixed to its upper end.

Reference numeral 10 denotes a pair of L-shaped left and right steering frames, whose vertical shafts are rotatably attached to vertical holes at both ends of the front wheel mounting frame 6, and a nut 11 is attached to the upper end via a washer.
is screwed in and fixed to prevent it from coming off downward, and the outer axle 1 at the lower end of both steering frames 10
The front wheel 4 is rotatably attached to 2 so as not to come off.

Further, a knuckle arm 13, which is the lower side of the front wheel mounting frame 6, is fixed forwardly to the vertical axis of each steering frame 10, and the upward movement of the steering frame 10 is prevented by this arm 13.

Reference numeral 14 designates a tie rod, which is bent upward at both ends and rotatably fitted into the hole at the front end of each knuckle arm 13, and is made to protrude above the arm 13 to form a restriction piece 15; This fixes a washer on the upper side of the knuckle arm 13 to prevent the restriction piece 15 from coming off from the knuckle arm 13.

Reference numeral 16 in FIG. 2 denotes a tire house on both sides of the front part of the lower vehicle body 2, and its inner wall is connected to the contact surface 17 of the limiting piece 15.
shall be.

The center part of the tie rod 14 is bent forward into a chevron shape as shown in FIG. Engage the engaging piece 19 fixed forward to the lower end of the handle shaft 8.
The tie rod 14 is configured to be moved left and right by the rotation of the tie rod 14.

The steering restriction device of this invention has the above configuration,
When the steering wheel shaft 8 is turned by the steering handle 9, the engagement piece 19 at the lower end moves the tie rod 14 to the right or left, and via the knuckle arm 13 turns the axle shaft 12 of the steering frame 10 to the right or left.

When the nutkul arm 13 rotates in this way,
The limiting piece 15 at the tip is the abutting surface 17 of the lower vehicle body 2.
limit further rotation.

As described above, this invention has a limiting piece 15 that limits the steering angle of the front wheels 4 projected onto the knuckle arm 13, and this limiting piece 15 is brought into contact with the contact surface 17 of the lower vehicle body 2, etc. There is no need to attach a separate stopper to the front wheel mounting frame, etc., which simplifies the structure and reduces man-hours and the number of parts.

In the embodiment, both ends of the tie rod 14 are bent upward to form a limiting piece; however, the tip of the knuckle arm 13 may be bent upward to form a limiting piece.

Claims (1)

[Scope of Claim for Utility Model Registration] 1. Steering frames bent in an L-shape are rotatably attached to both ends of a front wheel mounting frame provided near the front of the bottom of a children's car, and both steering frames are turned outward. In children's automobiles, the front wheels are rotatably attached to the wheels, the ends of the knuckle arms protruding forward from each steering frame are connected by tie rods, and the tie rods are moved left and right by the steering handle. A steering restriction device for a children's car, which is configured to limit the rotation range of a knuckle arm by bringing restriction pieces projecting upward from the car body into contact with contact surfaces on both sides of the car body. 2. In the steering control device for a children's vehicle as set forth in claim 1 of the utility model registration claim, the steering control device is limited by bending both ends of the tie rod upward and inserting the tie rod into a hole at the tip of the knuckle arm so as to protrude above the knuckle arm. A piece.
